Double Walled Tube Heat Exchangers

​Elanco's unique double walled tube has a purge passage coiled through the middle of the tube wall. The bi-walled tube should be used when the heat exchanger is part of critical equipment design or is primarily safety related. Appications where the tube is used are as follows:

When the exchanger is in contact with hazardous material i.e., cooling Tritium gas at a nuclear facility.

When the process and cooling sides react violently i.e., water and sodium.

When an exchanger failure would incur expensive downtime i.e., feed water exchange at a utility power plant.

When an exchanger failure would seriously damage expensive equipment i.e., an oil cooler on a gas turbine.
